Explanation:
The given chemical equation is:
Fe(CN)63-(aq) + Re(s)-> Fe(CN)64-(aq) + ReO4-(aq)
Consider oxidation half reaction and balance it first in acidic conditions:
Add water on the left side to balance the O-atoms:
Add protons on the right side to balance H-atoms:
To balance the charge add electrons:
------------(1)
Reduction half reaction:
Fe(CN)63-(aq) -> Fe(CN)64-(aq)
Add electrons to balance the charge:
---------------(2)
Multiply equation(2) with seven :
------(3)
Add (1) and (3)
Add 8OH- on both sides:
It becomes:
This is the final equation in the basic medium.
Re(s) is oxidised. So it is the reducing agent.
Fe(CN)63- is reduced.It is the oxidising agent.
Answer is none of the above
Nuclear energy is formed by the splitting of a heavy atom into lighter atom the result of which is the release of energy in the process – this energy is the nuclear energy that binds the nucleons together. With many atoms in a single fuel rod, the energy amounts to millions and billions of orders of magnitude. This energy is released and used to heat water that turns to steam and used to move turbine generators that produce electricity.
First, we need to find the atomic mass of
.
According to the periodic table:
The atomic mass of Carbon = C = 12.01
The atomic mass of Hydrogen = H = 1.008
The atomic mass of Oxygen = O = 16
As there are 6 Carbons, 12 Hydrogens and 6 Oxygens, therefore:
The
molar mass of
= 6 * 12.01 + 12 * 1.008 + 6 * 16
The
molar mass of
= 180.156
grams/moleNow that we have the molar mass of
, we can find the grams of glucose by using:
mass(of glucose in grams) = moles(of glucose given in moles) * molar mass(in grams/mole)
Therefore,
mass(of glucose in grams) = 2.47 * 180.156
mass(of glucose in grams = 444.99 grams
Ans: Mass of glucose in grams in 2.47 moles =
444.99 grams

Convection is a type of heat transfer that is driven by the flow of liquid, or by a solid or weak material. These convection cells that flows in a circular direction are caused by the initial heating of earth's core. Earth is hot due to the original formation, and what keeps the heat circulating is radioactive decay. As unstable elements decay, they release energy and heat, which promotes convection cells in earth's mantle [hope this helps].
